Plastic refractories

Plastic refractories
THERVEK RM（Ramming）

Plastic ramming refractory consisting of carefully selected refractory aggregate and highly-pliable clay, adjusted into a workable form with the addition of moisture. The product is supplied in 50mm-thick slices.

Place slices of the product in the form, and apply to the refractory lining walls by ramming them firmly into place with a pneumatic rammer. Prepare forms for ramming application.

Clay bonded plastic refractories maintain their shape after ramming due to the adhesive power of the clay. After firing, gives the refractories their strength (i.e. heat setting).

Characteristics

Plastic refractories do not require mixing, and can be rammed as they are.

THERVEK HR（Plastic gunning）

Plastic gunning refractory consisting of carefully selected refractory aggregate and highly-pliable clay, adjusted into a workable form with the addition of moisture. The product is supplied in granular clay-like form.

Using AGC Plibrico’s independently developed specialized gunning machine (HyRATE unit), it is now possible to apply plastic refractories by gunning (HyRATE method), achieving a drastic improvement in installation efficiency in comparison with ramming.

Clay bonded plastic refractories maintain their shape after ramming due to the adhesive power of the clay. After firing, gives the refractories their strength (i.e. heat setting).

THERVEK PAT（Patching）

Patching repair material with superior adhesive properties

Plastic refractory for patching use, consisting of a combination of carefully selected refractory aggregate and phosphate binder, adjusted into a workable form.

Patching refractories are adjusted to a softer consistency than ramming plastic refractories, and used for repairing small-scale damaged sections of refractory lining walls by patching (i.e. manual filling).

After application, patching refractories are fixed in place by the strong adhesive power of phosphate. When these refractories are heated to temperatures in excess of 350℃, a phosphate condensation reaction occurs, significantly improving the strength of the refractory (i.e. heat setting).

Characteristics

These refractories are affixed firmly to the repair area by the strong adhesive power of phosphate.

After heating, patching refractories display extremely strong adhesive strength in their adhesion to the base material.

Patching in this way enables you to prolong the service life of your refractories by performing easy repairs.
